    Real-Time Automotive Networking

    July 2, 2025
    Time-sensitive networking is key to real-time automotive applications
    Related To:

    Automotive applications need to run in real-time, and these days new vehicles utilize Ethernet to connect sensors, engine control units (ECUs) and advanced driver-assistance systems (ADAS). Time-sensitive networking (TSN) Ethernet connections provide deterministic and low-latency connectiivity required for this type of application. 

    The following content addresses TSN in an automotive context. 

    Single-pair Ethernet presents a lighter, lower-cost alternative to RJ-45/CAT5 and 6 that's typically used in computing applications.
